I'll make it very simple. It doesn't matter what brand as long as SAE oil, which is just about anything on the market. Pennzoil, Quaker state, Mobil, Valoline, and so on. Even store brand such as Auto Zone Super Tech (Wal Mart) will work just fine. Pick whatever is on sale. It's more important to change it, than what brand it is.
Nobody can answer that question, without knowledge on how and where you drive. If all of the trips are 10 miles or less and you live in North Dakota one answer, if on the other hand you live and drive in Orem Utah and do all hway another answer. Most people are leaning towards syn on these forums, why not it is almost as cheap as conv. oil these days. Just check your Wally oil section.
